ECG T-wave amplitude, muscle tension, and heart rate concomitants of conditioned suppressionTwo preliminary studies showed that T-wave flattening and masseter muscle tension reliably indexed the cardiac sympathetic and skeletal muscle components of a conditioned emotional response. These indices were then...
Although often ignored, assessment of the electrical axis is an integral part of ECG interpretation. The electrical axis reflects the average direction of ventricular depolarization during ventricular contraction. The direction of the depolarization (and thus the electrical axis) is generally alongside the...
The amplitude of T-wave flattened significantly after atropine. It is concluded, that the ECG T-wave amplitude reflects the balance of sympathetic and parasympathetic nervous activity during isoflurane anaesthesia. The use of the decibel transformation and confidence intervals seems to be a relevant ...
However, it represents an artifact called “pseudo double T wave”. The cause is unknown but most likely due to abnormalities at the interface between surface electrodes and skin tissue. The diagnosis of ECG artifacts requires meticulous examination of the tracings coupled with a thorough knowledge...

Hi, I have trouble making my matlab loop count only my R waves of the ECG signal. The loop counting the peaks is: thr = 40; beat_count = 0; for k = 2 : length(sig)-1 테마복사if( sig(k) > thr && sig(k-1) < thr) beat_count = beat_count + 1; ...
For this aim, the ECG amplitude modulation and the baseline wander in the ST-T segment are approximated by a scaling factor applied to the T wave added to a constant. Thanks to this simplification, the proposed global model of each ST-T segment is constituted by the scaled T wave, an ...
The spectral analysis of signals is currently either dominated by the speed–accuracy trade-off or ignores a signal’s often non-stationary character. Here we introduce an open-source algorithm to calculate the fast continuous wavelet transform (fCWT). T
ECG, computer analysishyperacute T wavesHyperacute T waves (HATWs) have been described as tall-amplitude, primary T-wave abnormalities sometimes seen in the early phases of transmural myocardial infarction. Despite numerous human and animal studies addressing the presence and significance of HATWs, ...
The electrocardiogram (ECG) morphology determines the overall activity of the heart and is the most widely used tool in the diagnostic processes. T wave is a crucial wave component that reveals very useful information regarding various cardiac disorders. In this paper we have proposed a novel T ...
